Definitions

  • the invention relates to a composite driving belt provided with a carrier and a plurality of transverse elements assembled slidably thereon, the carrier comprising one or more band packages provided with a plurality of endless metal bands disposed radially around each other.
  • Such a driving belt may in particular be applied in a variable transmission, whereby the driving belt runs over pulleys, the substantial conical sheaves of which are adapted to be displaced axially relative to each other so that the running diameter of the driving belt over the pulley may vary.
  • such a driving belt is under a very high tension, on the one end to ensure a proper frictional contact between the pulleys and the transverse elements, and on the other end to properly conduct the transverse elements in the straight part of the driving belt.
  • At least one of the metal bands of the carrier is provided with a surface profiling, said profiled side abutting a band side without such surface profiling.
  • the metal bands of the band package When the driving belt runs over pulleys having different running diameters, the metal bands of the band package have a mutual speed difference, at least in situ of one of the pulleys.
  • This speed difference may in practice be more than 1 meter per second between two successive bands (disposed around each other).
  • the inner bands are pressed onto each other with substantial force, since the pressure force on a band is built up by all bands disposed outside (i.e. therearound).
  • the surface profiling comprises grooves, which in practice provide good results.
  • the roughing value of the surface profiling lies between 0.30 and 0.75 ⁇ m Ra (measured according to CLA method) and preferably between 0.45 and 0.55 ⁇ m Ra.
  • the grooves are disposed in crossing sets. A good result is achieved when the metal bands are provided with the surface profiling only at the radial inner side.
  • the invention furthermore relates to an endless metal band for a driving belt which band according to the invention is provided at least at one side with a surface profiling, preferably comprising grooves. Said grooves according to the invention may be disposed in crossing sets viz. at the radial inner side of the band.
  • the invention relates to a method of applying a surface profiling on the radial inner side of an endless metal band for a driving belt.
  • the metal band is rolled between rollers, one roller being fitted with a surface profiling on the circumferential surface.
  • the drawing shows diagrammatically an endless metal band.
  • the width of such a band may e.g. range between 5 and 20 mm and the thickness between 0.15 and 0.25 mm.
  • the diameter of the band (in circular condition) may e.g. range between 150 and 300 mm. Such dimensions are not expressed in the diagrammatic drawing.
  • the endless band according to the drawing has a exterior side 1 and an interior side 2.
  • the inner side 2 is provided with a surface profiling of crosswisely disposed grooves.
